AUTOMATIC-DISENGAGING MOTOR-PLOW.

Application filed November 24, 19 14. Serial No. 873,743

To all whom it may concern:

Be it known that I, FRANK POTTER, a citrzen of the United States, and residing at' the plow shovel, which is adapted to moveupwardly to elevate the plow when an'obstruction is engaged, and a trip for elevating the means.

With the above and other objects in view the: invention comprises certain new and useful constructions,combinations, and arrangements of parts,'clearly described 1n the following specification and fully-illustrated in the accompanying drawings, in which Figure l is a side elevation of a plow construction provided with the improvements. 2 is a top plan view thereof. Fig. 3 a detail perspective View of a runner bar and roller guides therefor.

Referring to the accompanying drawings illustrating the practical application of the invention 1 designates the front and rear plow standards, which carry the plow shovels 1. The standards 1 are secured to the plow beam 10, which connected to pend-' ant brackets 10" secured to the runner bar 11'.

The standards 1 have a pivotal-connection with the brackets 10, and at least one of said standards is providedwith a plurality of bolt holes whereby the same may be adjustably connected with the beams 10.

The runner bar 11 works on lateral guide rollers 11, which are arranged on the pendant brackets 11", which have their upperends rigidly secured to the frame beam A. A link 11 is pivotally connected at its upper end to the runner bar 11 and at its lower end to the beam 10, 1

The frame beam, A is provided at its rear end with a supporting wheel A and its forward end is supported by wheels A mounted on an axle A A suitable motor or engine B is mounted upon the frame A, and-- a suitable transmission ;,gear, of the plane- I Specification of- Letters Patent.

my type, as indicated at 5 is provided for transmitting motion from the motor or engine to the wheels A The gear 5 is provided with a reverse mechanism and a clutch. An arm 8 is connected at its forward end tothis reversing mechanism and clutch, and at its rear end'it is connected with the operating lever 6 ;b y means of the arm 7 The lever 6 is pivoted to the frame A at 9 and projects downwardly and has an operating connection with the plow beam 10. The plow beam 10 is connected at its forward end with a supplemental beam 2,

by a flexible joint, and this supplemental beam isflexibly connected to the spring trip, indicated at 3, which is mounted on the forward end of the frame A.

The spring trip is of such construction that an unusually obstinate obstruction is required to "operate it in its first movement,

and after being started in operation works more easily. When the plow shovels strike .an' obstruction the engagement tends to cause a forward movement of the beam 10, to which the shovels are connected. If the obstruction resists further movement of the plow shovels the spring trip will be released andthe beam 10 is then permitted to move rearwardly, carrying the runner bar 11 with it, and as the lever-6 is connected with said beam 10' and pivotally secured to the frame beam A as at 9, the upper end of said lever is also forced in a forwardly-direction, thus forcing the clutch out of engagement with the gear 5, through the medium of the arms 7 and 8, thus permitting theengine to operate freely while the-machine in general is brought to a standstill. v

Suitable means may be provided for elevating the plow shovels. The engine may be reversed so as to drive the motor plow rearwardly.

The'form of-spring trip used is identical with thatishown in the catalogues of the Oliver Chilled Plow- Works, and which is applied to my improved plow construction 1n the manner disclosed in the drawings,
